IO.classLocation[A: Manifest]: URL

On JDK 11 onwards the class location from a Java Module returns a jrt URL, for example jrt:/java.base, which cannot convert to java.io.File, but can be represented as an NIO Path.

To work around this, sbt 1.2.4:

• deprecates IO.classLocationFile[A: Manifest]: File
• brings back IO.classLocation[A: Manifest]: URL
• adds IO.classLocationPath[A: Manifest]: java.nio.file.Path and IO.classLocationFileOption[A: Manifest]: Option[File].

All of them return the directory, Java module, or the JAR containing the class file for type A (as determined by an implicit Manifest).
